Some time ago `AudioProcessorValueTreeState` and `AudioProcessorParameter`(WithID) did not exist.  
So I’m curious what **you** used in the last plugin you coded :

And what would you _recommend_ using :

Currently i use AudioProcessorParameter, but i want to use AudioProcessorParameterWithID in the future.

I can’t use AudioProcessorValueTreeState, because it think it has a few design flaws.

- if the parameter uses a interval, the quantized (stepped) values are stored internally.

I think this is problematic, from a hosts perspective, it sets a certain float value, and gets a quantized value back.

(correct me if i’m wrong)

- A function for storing normalized frequency values in a logarithmic way is missing (not skew)

I’m a huge fan of ValueTreeState, mostly because you basically get parameter save/restore and undo/redo for free. But like @chkn said, it definitely has some flaws that have to be worked around.

You can try this for undo/redo - [AudioProcessorUndoAttachment for JUCE · GitHub](https://gist.github.com/yairchu/0a70e553af6176b2f6af)  
It provides a class `AudioProcessorUndoAttachment` which listens to an `AudioProcessor` and adds all the parameter changes to an `UndoManager`.
